Not directly but it can be done.

The brakes are the same but the backing plates are different, and you can't put a 9 bolt disc backing plate directly on a 10 bolt drum axle tube flange.

is there some parts you can buy to swap from 9 to 10 bolt and keep your PBR setup on the 10 bolt?

The correct backing plates can be purchased from several sites, to include the following:

The above site also makes a "hassle free" kit:
